Temperature and light intensity measured at each transplant site during a reciprocal transplant experiment conducted at three sites in Turneffe Atoll, Belize from February to July 2022

We sought to investigate the role of genetic, intra-clonal, and environmental variation in driving variation in fitness-related traits in the Caribbean thin finger coral, Porites divaricata (Taxonomy ID: 262287). We conducted a reciprocal transplant experiment whereby fragments from individual coral colonies of known genetic background were transplanted to three sites from February to July 2022. These sites included two mangrove sites and one reef site at Calabash Caye, Turneffe Atoll, Belize. Prior to and post-transplanting, fragments were measured to determine growth rate over this time. Coral fragments were also photographed to determine red channel intensity, which serves as a proxy for chlorophyll density. This dataset contains environmental information about each transplanted site over this time period, based on loggers that recorded temperature and light levels. This data was collected by scientists at the University of Texas at Austin and the University of Belize. A related dataset contains the measures of these two coral traits (coral fragment growth and chlorophyll density (red channel intensity)) for each coral individual and also contains metadata about the genotype, origin site, transplanted site, rope at transplanted site, and age.本研究旨在探究遗传变异、克隆内变异与环境变异对加勒比细指珊瑚（*Porites divaricata*，分类学ID：262287）适合度相关性状变异的调控作用。我们于2022年2月至7月开展了互易移植实验：将已知遗传背景的单个珊瑚群落的组织片段移植至三处实验位点，该实验位点位于伯利兹特纳夫环礁的葫芦礁（Calabash Caye），包含两处红树林位点与一处礁岩位点。移植前后均对珊瑚片段进行测量，以计算该阶段的生长速率；同时对珊瑚片段拍摄数码影像，以测定其红光通道强度，该指标可作为叶绿素密度的替代表征。 本数据集包含此时间段内各移植位点的环境监测数据，数据来源于记录温度与光照水平的环境记录仪。本数据集由德克萨斯大学奥斯汀分校（University of Texas at Austin）与伯利兹大学（University of Belize）的科研团队采集完成。 相关数据集包含每株珊瑚个体的两项性状测量数据，即珊瑚片段生长速率与叶绿素密度（红光通道强度），同时包含基因型、起源位点、移植位点、移植位点处的固定绳索以及个体年龄等元数据。
